Ingredients You’ll Need
Here’s everything you need to create a pork loin that’s tender, flavorful, and coated in a beautifully tangy balsamic glaze that tastes far more complex than the prep requires:
- 3 lb boneless pork loin – A lean, protein-rich cut that becomes incredibly tender when cooked low and slow. Its mild flavor makes it the perfect canvas for bold glazes and herb blends.
- 1 tsp salt – Not just for seasoning—salt draws out moisture and enhances the natural flavor of the pork as it cooks.
- 1 tsp paprika (sweet or smoked) – Paprika adds a gentle warmth and a touch of earthy sweetness. If you use smoked paprika, it deepens the overall flavor and brings a rustic, smoky note to the dish.
- ½ tsp onion powder – Offers a mellow, background sweetness that builds complexity without overpowering.
- ¼ tsp black pepper – Just enough to cut through the sweetness of the glaze and bring a subtle heat to balance the flavors.
- ⅓ cup chicken broth – Helps keep the pork moist and adds depth to the pan juices that form during cooking.
- 4 tbsp olive oil, divided – Used in two ways: first for searing the pork, then blended into the glaze to help it adhere beautifully.
- 3 tbsp balsamic vinegar – The hero of the glaze—tangy, sweet, and rich with depth. It caramelizes gently as the pork cooks, forming an irresistible coating.
- 5 cloves garlic, smashed – Infuses the glaze with a warm, savory aroma that lingers through each bite.
- ½ tbsp Italian seasoning – A fragrant mix of dried herbs that gives the dish a familiar, Mediterranean warmth.
Pantry Tips: Choose a high-quality balsamic—preferably aged—for a richer, more nuanced glaze. Fresh garlic is best here; it’s more pungent and vibrant than jarred. And if you want a smokier vibe, don’t hesitate to use smoked paprika in place of regular.
Can I use apple cider vinegar instead?
Yes, you can but expect a slightly fruitier, less intense result. Balsamic adds depth and sweetness that cider vinegar lacks, so while it works in a pinch, it won’t deliver quite the same magic.
How to Make Slow Cooker Pork Loin with Balsamic Glaze
This recipe comes together in five simple but flavor-packed steps. Let’s walk through it:
- Step 1: Prep the Pork
- Begin by patting the pork loin dry with paper towels—moisture on the surface can prevent a proper sear. In a small bowl, combine the salt, paprika, onion powder, and black pepper. Rub this spice blend thoroughly over every side of the pork loin. This step not only seasons the meat but creates a flavorful crust when seared.
- Step 2: Sear for Flavor
- Heat 1 tablespoon of olive oil in a skillet over medium heat. Once hot, place the pork loin in and sear it on all sides—about 2 to 3 minutes per side—until it develops a golden-brown crust.
- Pro Tip: Don’t skip this step. It helps lock in juices and gives the final dish a rich, caramelized edge that adds serious flavor depth.
- Step 3: Make the Glaze
- In a blender, combine the remaining 3 tablespoons of olive oil with the balsamic vinegar and smashed garlic cloves. Blend until smooth, then stir in the Italian seasoning for a fragrant finish.
- Step 4: Assemble & Cook
- Pour chicken broth into the base of the slow cooker. Place the pork loin fat-side up, brush generously with the glaze, then cover and cook on LOW for 4–5 hours or HIGH for 3 hours.
- Step 5: Rest & Serve
- Once done, let the pork rest for 10 minutes before slicing. Spoon over the rich pan juices to finish.
FAQ: How do I know when it’s done?
Use a meat thermometer. Pork is perfectly cooked when the center hits 145°F.y.
Tips & Tricks for Juicy, Tender Pork
Getting that fork-tender, melt-in-your-mouth pork isn’t just about cooking time—it’s about smart technique at every step. These tips will help you make the most of this recipe every time.
- Sear First: Always take a few extra minutes to brown the pork before slow cooking. That golden crust isn’t just pretty—it locks in moisture and builds a rich base of flavor that slow cooking alone can’t deliver.
- Don’t Overcook: Pork loin is a lean cut, which means it’s less forgiving than fattier pork shoulder. Cooking it beyond 145°F can make it dry and stringy, so monitor it closely near the end.
- Use a Meat Thermometer: This one tool can make or break your pork game. Internal temperature is the most reliable way to know when it’s perfectly cooked—safe, but still juicy.
- Let It Rest: After cooking, let the pork sit for about 10 minutes before slicing. This pause allows the juices to redistribute evenly, so each bite stays moist.
Leftover Magic:
Use leftovers creatively shred the pork for tacos, layer it on mashed potatoes, or toss it into pasta with roasted veggies.
Can I freeze leftovers?
Yes! Slice or shred and freeze in airtight containers for up to 3 months. Reheat gently in broth or microwave to keep it tender.
Substitutions or Variations
One of the best things about this slow cooker pork loin recipe is how flexible it is. Whether you’re adjusting for diet, flavor preferences, or what’s in your fridge, these simple swaps keep the dish interesting without compromising taste.
- Swap the Cut:
Don’t have a pork loin on hand? No problem. You can use pork shoulder if you prefer something richer and more marbled—it’s perfect for shredding and has a deeper flavor. On the flip side, pork tenderloin is leaner and more delicate, but cooks faster, so you’ll need to reduce the cook time to avoid dryness. - Change the Flavors:
Feel free to make the herb profile your own. Try swapping out Italian seasoning for a mix of rosemary and thyme for a more classic roast flavor. Craving heat? Add red pepper flakes to the glaze for a subtle kick. For a sweeter glaze, stir in honey or maple syrup with the balsamic for a bold twist. - Make It Dietary Friendly:
Need it gluten-free? Just ensure your chicken broth and balsamic vinegar are certified GF. Going keto? Opt for a sugar-free balsamic or reduce the vinegar slightly.
Can I make this in an Instant Pot?
Yes! Sear using the sauté setting, then pressure cook on HIGH for 35 minutes with a 10-minute natural release.
Frequently Asked Questions (FAQ)
Can I make this ahead of time?
Yes, you can season and sear the pork the night before. Store it in the fridge and place in the slow cooker the next day.

Garlic mashed potatoes
Roasted Brussels sprouts
Wild rice or couscous
